OUTSIDE METAL CAR-ROOF.

' Specication of Letters Patent.

Application filed April 14, 1909. Serial No. 489,836.

. the weightof theV running board; to provide for the `fastening of the ruiming board g and to, secure other advantages hereinafter up aring. l l The` inventionv consists principally `in .grooved capsstraddling the ridge seam throughout the full width of the sheets and adapted to be held vby the 'corner caps.

It also consists in modifying the ends of the endinost'seam caps to provide for the fastening thereof. v h It also consists adapting the corner caps to secure the running board saddles; and it alsoconsists inthe parts and inthe arrangements and combination of parte hereinafter described and claimed.

In the accompanying drawing, wherein @like symbols .refer to like parts wherever they occurf-.Figure 1 is a vertical longitudinal sectional View of the end portion of a car embodying my invention; Fig. 2 is a side View of a corner cap showing 1n section Aa running. boa-rd saddle engaged thereby; 351.

Fig.. 3 isa detail View of the bolt for securing the corner cap, the head of said bolt being shown in section; Fig. 4 is an elevation of a corner ycap with the. running-board f'saddle interlocked therewith; Fig. 5 is a plan View of-a corner cap with a running .board saddle interlocked therewith; Fig. 6 isa side elevation of the endmost ridge cap with a running board saddle shown in sec tion; Fig. 7 an end' elevation of the endmost ridge cap; Fig. Sis a sideelevation of, a ridge cap for the intermediate sheets; and' Fig. 9....is an end elevation of the ridge cap.

In the present invention, the metal roof4 sheets; l rest upon a Wooden sheathing 2 which.. is supported by a sub-structure of common type. The metal roof sheets are arranged transversely of the car and are connected at the sides by raised seams or ribs 3 of any. suitable type. Thesheets extend upwardly from the eaves to the ridge where they are likewise connected by raised seams or ribs of any suitable ty.pe. V As illustrated in the drawing, these yridge seams are formed by the overlapping ot relient'upwardlyprojecting anges on the ridge endsfof the sheets. The sheetsare'movahly heldin place at the eaves by clips or other suitable' devices; and they are movahly held in position at the ridge by corner caps 5 having fourwny grooves or channels therein adapted to., accon'nnodat'e the ridge and transverse sems.

In consequence of this well known' method of fastening the metal sheets, theyare free to move to a limited extent relatively to the wooden sheathing.

In order to protect the ridge'portions of the sheets, a seam cap G is providedtherefor. This seam cap is a strip of sheet metalhaving a longitudinal groove therein of suitable din'iensions to accommodate the ridgeseam or upwardly extending anges of the roof sheets.- rlhe ends of these seam caps reach v close to the side Hanges of the roof sheets so that said ends are covered by the corner caps. The marginal portions of said seam cap lie iiatwise against the roof sheets; and

as the end portions thereof arc.of'substantially the saine width as the corner caps, the corner caps bear solely againstv them. By this arrangement, the seam caps constitute wear plates and to a considerable extent relieve the rootI sheets ofthe wear andother eHect-s that would he produced if theV cornerA caps bear directly on the roof sheets.

Each of the corner caps has a bolt hole in its topmost portion atthe point of intersection of its grooves oi` channels." Around the margin of this hole is formed a raised rib 8 of annular or polygonalcontour. Extending downwardly through said bolt hole is a threaded bolt 9 whose lower end `extends through the ridge pole 10 of the car and is secured 'by a suitablefnut 11., The head or ,upper wend of the bolt is provided .onl its under surface with a"grOOveorChanHel 12. .adapted to.. l'eeeirei theurtffd'in corn-er' cap. "By" this 'arrangement '-f"th`e"fliolt hole is protected from the weather.'

Projecting horizontally from the upper portion of the corner cap in the direction of the length of the car is an angular hook or securing member 13 preferably integral therewith. The outer end portion 14 of this securing member is turned downwardly; and located between the body of the corner cap and the downturned portion of the hook is a ridge saddle 15. The lower portion of lb stufe' this ridge saddle is beveled or inclined to i and I do not wish to be restricted to the deconform to the pitch of the ear roof, and the top. of the ruiming board vsaddle is immediately under the horizontal projecting portion 13 of the corner cap. In some cases, it 1s deslrable to groove the upper surface otl the running board saddle (as illustrated in Fig. 4) so that the top thereof may be ilus-h with or slightly above the top oi the corner cap. B v this arrangement, the respective running board saddles are held in place b v the corner 'ap and alongside thereof, without being materially weakened and Withoutimposing their Weight upon the corner caps.

1n the case of each ot' the endinost seam caps 1G, special provision is made for securing the ends thereof. The inner end ot' the Vendmost seam cap has longitudinal slits of suiiicient length to reach beyond the corner cap; and the slit corner portions 1T ot said seam ycap are turned up alongside ot' the running board saddle'and are secured thereto by nails or other suitable means. The outer end of each of the endmost scam caps is bent downwardly, and the dowi'iturned portion 1S thereoil is nailedV or otherwise suitably secured to the end molding. The downturning ot' the end is etl'eeted in such manner that the seam is completely closed by the material. ot' `the seam cap. so that the weather is excluded from said ridge seam. Resting upon the running board saddles are suitable running boards if) whose ends are supported by brackets 20 mounted on. the ends of the car.

Among the advantages ofthe present invention, it is noted that the ridge seams are fully protected throughout the width of the sheets and that the protective caps extend beneath the corner caps and are secured thereby. It is also noted that, as there is no material mutilation of the running board saddles, they may be made of thinner stock than has heretofore been the practice. 'It is also noted that', as the Weight of the running boards is taken from the corner caps there is less risk ofl the roof sheets being pinched by the corner caps, and besides, the weight on the roof sheets is distributed over a larger area. It is also noted that, on account of the simplicity ot' the several devices there/is little risk of careless Workmen making mistakes in the application thereof.

Obviously the construction hereinbefore described admits of considerable modification without departing frommy invention tails above set forth.

What I claim isz, l. A car roof comprising root' sheets extending froni eaves to ridge and movably connected at their sides and inner ends by raised seanis, grooved seam caps covering the ridge seams, grooved corner caps at the ridge covering the end portions of said ridge caps and the side seams, and running board saddlesl arranged transversely of the car and secured to said corner caps alongside thereof, the inner ends of the side portions of the endlost seam cap being turned up and secured to the adjacent running board saddle.

2. A car roof comprising root' sheets ex tending from eaves to ridge and movably connected at their sides and inner ends hy raised seams, grooved seam caps covering the ridge seams, the endmost ridge cap being secured at its outer end to the end of the cai', grooved corner caps at the ridge covering the adjacent en d portions of 'the ridge caps and the inner ends of the side seams, and running board saddles arranged loosely,

transversely7 of the car alongside of the corner caps.,` each of said corner caps being secured to the top ot' the ear by a bolt passing therethrough and each ot said corner caps also having a saddle portion adapted to f overhang the adjacent running board saddle to hold the same in place, the inner ends ot' the side portions of the endniost ridge cap being secured to the adjacent running board saddle.

3. A car roof comprising roof sheets extending from eaves to ridge and lnovably connected at their sides and ridge ends by raised seams, and grooved corner caps at the ridge covering the endy portions of said ridge and side seams, and VWear plates intervening between said corner caps and said roof sheets, said wear plates being grooved to bridge the ridge seam and extending substantially. the full Width of a sheet and being of substantially the same Width as the corner cap.

In Witness whereof I have signed my name to this specification in the presence of two subscribing Witnesses this 12th day of April, 1909, at Pittsburg, Pennsylvania. Y

PETER H. MURPHY.
